  In the above conventional example, when there are many types of terminal abnormalities that occur at the same time, all error codes and device identification numbers are displayed and confirmed by the forward operation of the separate display feed switch. There is a problem that it takes time to confirm the number.

  An object of the present invention is to provide a monitoring control panel capable of grasping all types of abnormality in a short time even when a large amount of abnormality factors occur.

The monitoring control panel of the present invention includes a state detection means for detecting an abnormal state of the monitoring control panel and / or an abnormal state of each terminal connected to the monitoring control panel, and an error code of a predetermined number of characters for specifying the abnormal content, Or a display device of a predetermined number of characters for displaying the error code and a device identification number of a predetermined number of characters that is a number for identifying an abnormal device, and any one of a plurality of abnormal states detected by the state detection means If the display unit displays one error code or the device identification number, and the state detection unit detects a plurality of abnormal states, and if there is no need to display the device identification number, the error code is sequentially displayed. If it is necessary to display the device identification number, display the error code, switch the display to the device identification number, and then add another error code. By switching sequentially displayed to a control means for displaying on the display device, switching the display of the Erako earthen other corresponding to all of the abnormal condition is detected the upper Symbol equipment specific number, at predetermined time intervals comprising a control means for displaying on the display device, an error code identifying the abnormal content, or a selection switch for selecting a display pattern to the error code and the device identification number, is displayed on the display unit Te, the selective By inputting the switch for the second time, when the same error code is continuous, the control means switches the representative error code including the same error code one by one every predetermined time to the display. It is characterized by being displayed.

  According to the present invention, only the error code is forwarded by the switch operation, so that all types of abnormality can be visually recognized in a short time, and therefore, even when a large number of abnormality factors occur, There is an effect that the type of abnormality can be grasped in a short time.

It is a figure which shows the main structures of the monitoring control board 100 which is Example 1 of this invention. FIG. 4 is a schematic diagram showing switches, indicator lights, etc. in the switch operating means 40. It is a figure which shows the list of abnormality alarms. It is a flowchart which shows operation | movement of the said Example. It is a figure which shows the display patterns 1-3 in the case of displaying an error code.

  The modes for carrying out the invention are the following examples.

  FIG. 1 is a diagram showing a main configuration of a monitoring control panel 100 that is Embodiment 1 of the present invention.

  The monitoring control number 100 is, for example, a smoke alarm panel having substantially the same function as that of a fire receiver of an automatic fire alarm system, to which a suction type smoke detector is connected. Means 20, 7-segment display 30, switch operation means 40, and selection switch 41 are provided.

  The state detection means 10 processes an output signal from a sensor or the like, and detects an abnormality if an abnormality has occurred in the sensor or the like. The state detection means 10 may be provided in the main control means 20.

  The main control unit 20 causes the 7-segment display 30 to display an abnormality alarm corresponding to the type of state detected by the state detection unit 10. When a fire detection signal is received from the smoke detector, an alarm sound is generated.

  The switch operating means 40 includes an AC power lamp (green), a switch caution lamp (red), an abnormal representative lamp (yellow) 4, an environmental abnormal representative lamp (red) and a caution representative lamp (red) due to the smoke density of the sensor, and a fire. It has a representative lamp (red), a 7-segment display 30, a standby power test switch, a fire / abnormal test switch, a fire / abnormal signal cut-off switch, and the like. Here, an example of the display color of each indicator lamp is shown in parentheses. A selection switch 41 is also provided. The selection switch 41 may also be used as a line selection switch for a fire test for confirming whether the display and alarm function of the monitoring control panel 100 operates normally.

  The 7-segment display 30 displays an error code constituting an abnormality alarm, or an error code + a device identification number.

  When an abnormal alarm is displayed on the 7-segment display 30, the selection pattern 41 is operated by a predetermined method to select a display pattern for displaying an error code and a device identification number. In the first embodiment, the display patterns are the display pattern 1, the display pattern 2, and the display pattern 3 for confirming all abnormal contents in a shorter time than usual when an abnormality has occurred. One display pattern is selected from these by operating 41.

  FIG. 2 is a schematic diagram showing switches, indicator lights, etc. in the switch operating means 40.

  The switch operating means 40 includes an abnormal representative lamp 4, a 7-segment display 30, and a selection switch 41. 2 includes the selection switch 41. However, the selection switch 41 may be provided outside the switch operation means 40.

  FIG. 3 is a diagram showing a list of abnormality alarms.

  FIG. 3 shows abnormality alarms, alarm items, and alarm contents. For example, E0, E1, E4, E6, and E8 are displayed as error codes only, or E0, E2, E3, E5, E7, and E9 are displayed as error codes + device identification numbers. The error code is composed of E and a number. E indicates that there is an abnormality, and the following numbers indicate the content of the abnormality. For example, the error code E0 indicates that the standby power supply is abnormal, and the error code E1 indicates that the circuit voltage is abnormal. The error code E2 indicates that the fuse is disconnected. If the external power supply fuse (FI) is disconnected, 00 is assigned as the device identification number after E2, while the sensor power supply fuses (FS1 to FS3). If E is disconnected, 01 to 20 are assigned as the device identification number (line number) after E2.

  Next, the operation of the above embodiment will be described.

  FIG. 4 is a flowchart showing the operation of the above embodiment.

  If an abnormality has occurred in S1, the error code (first time) of the first abnormality alarm is displayed. In S2, it is determined whether the selection switch 41 has been operated, and the selection switch 41 must be operated. For example, in S3, the error code (second time) of the first abnormality alarm or the device identification number is displayed. In S4, the error code (first time) of the next second abnormality alarm is displayed. If there is no next error code, that is, if there is no abnormality to be displayed next, the display returns to the error code (first time) display of the first abnormality alarm. In S5, it is determined whether or not all the abnormal factors have been recovered. If all the abnormal factors have been recovered, the process ends and waits until the next abnormal factor occurs. If even one abnormality factor has not recovered, the process returns to S2.

  In S2, it is determined that the selection switch 41 has been operated, and in S6, it is determined that the selection switch 41 has not been pressed for a long time (that is, it is determined that the selection switch 41 has been pressed shortly). The error code (first time) of the second abnormal alarm is displayed. That is, the display pattern 1 or the display pattern 2 is displayed. If there is no next error code, the process returns to the error code of the first abnormality alarm (first time). Display pattern 1 and display pattern 2 will be described later.

  If it is determined in S2 that the selector 41 has been operated with the selection switch, and if it is determined in S6 that the selection switch 41 has been pressed for a long time, the next representative error code is displayed in S8. That is, the display pattern 3 is displayed. If there is no next representative error code, the display returns to the error code (first time) display of the first abnormality alarm and the operation of the selection switch 41 is detected. The display pattern 3 will be described later.

  Next, display patterns will be described.

  FIG. 5 is a diagram showing display patterns 1 to 3 when displaying an error code.

  An example in which an error code is digitally displayed using the 7-segment display 30 will be described. In some cases, only the error code is displayed without displaying the device identification number, and the error code and the device identification number are sequentially displayed.

  FIG. 5 (1) is a diagram showing a blinking cycle of the 7-segment display 30. When the 7-segment display 30 is ON, it is turned on, and when it is OFF, it is turned off. Repeat every 1 second.

  FIG. 5B is a diagram illustrating a normal display state, and is a diagram illustrating a display example of the 7-segment display 30 when the selection switch 41 is not pressed.

  In this example, the error code “E1” blinks twice, the error code “E2” blinks once, the device identification number “01” blinks once, and the error code “E2” blinks once. That is, “E1” → off → “E1” → off → “E2” → off → “01” → off → “E2” → off is displayed. As shown in FIG. 3, the error code “E1” is an abnormality alarm indicating a circuit voltage abnormality alarm, and it is not necessary to display a specific device. Therefore, the device identification number is not displayed and the error code “E1” is displayed. Continue to display twice. As shown in FIG. 3, the error code “E2” is an abnormal alarm indicating a fuse disconnection alarm. In the example shown in FIG. 5 (2), the fuse in the line with the line number 01 is disconnected. The number “01” is displayed. The example shown in FIG. 5B is the same operation as the conventional example. In this case, there is a problem that it takes time to visually recognize all error codes and device identification numbers.

  FIG. 5 (3) is a diagram illustrating an example of the display pattern 1.

  In this example, when the error code “E1” is displayed, the selection switch 41 is pressed only once. When the selection switch 41 is pressed, the next error code “E2” is displayed instead of the displayed error code “E1”, and is displayed until the second lighting timing, and thereafter, as shown in FIG. Return to the normal display shown. That is, “E1” → “E2” → off → “01” → off → “02” → off is displayed.

  In display pattern 1, since the next error code of the currently displayed content or the device identification number to be displayed next can be visually recognized immediately after pressing the selection switch 41, the next error code or device identification number is visually recognized. The time until is shorter than the normal display.

  FIG. 5 (4) is a diagram showing another example of the display pattern 1.

  In this example, the error code “E1” is turned on and the selection switch 41 is short-pressed only once during the period when the 7-segment display 30 is not displaying. When the selection switch 41 is pressed, an error code “E2” to be displayed next is displayed and displayed until the end of the second lighting timing, and thereafter, the normal display shown in FIG. In the display pattern 1 shown in FIG. 5 (4), since the next error code or device identification number of the currently displayed content can be visually recognized immediately after the selection switch 41 is pressed, the next error code or device identification number is displayed. The time until visual recognition is shorter than the normal display.

  FIG. 5 (5) is a diagram illustrating an example of the display pattern 2.

  In this example, the error code “E1” is turned on and the selection switch 41 is pressed three times in a period not displayed on the 7-segment display 30 for a short time. When the selection switch 41 is pressed three times, the error codes “E2,” “E2,” and “E3” to be displayed next are displayed in order for a short time until the end of the second lighting timing. The display returns to the normal display shown in FIG. That is, “E1” → off → “E2” → “E2” → “E3” → off → “E3” → off → “E4” → off → “E4”.

  If the error code “E2” continues twice, it indicates that two fuse breaks corresponding to the error code “E2” have occurred.

  In the display pattern 2 shown in FIG. 5 (5), only the error code that should be displayed next to the currently displayed content can be immediately viewed, and the number of short presses can be forwarded and viewed together. The time until the next error code is visually recognized is sufficiently shorter than the normal display.

  That is, the display pattern 2 is a pattern in which only an error code is displayed by inputting the selection switch for a first time (continuous short press time) when an abnormality has occurred.

  FIG. 5 (6) is a diagram illustrating an example of the display pattern 3.

  In this example, the error code “E1” is turned on and the selection switch 41 is pressed for a long time during the period when the 7-segment display 30 is not displaying. For example, the long press is determined when the button is continuously pressed for 200 ms or longer. When the selection switch 41 is pressed and held, the representative error codes “E2”, “E3”, “E4”, and “E5” to be displayed next are displayed in order, and thereafter, the normal error code shown in FIG. Return to display. That is, “E1” → lights off → “E2” → “E3” → “E4” → “E5” → lights off.

  In display pattern 3, only representative error codes are displayed.

  In the display pattern 3 shown in FIG. 5 (6), the display contents after the currently displayed contents are displayed only for the representative error code and are continuously displayed without being turned off. The time for visually recognizing the representative error code is much shorter than that of pattern 1 and pattern 2. If the same error code is continuous, the representative error code is displayed only once. Thus, when the same error code is continuous, an error code displayed only once is referred to as a representative error code. That is, when an abnormality has occurred, by inputting the selection switch 41 for the second time (long pressing time), only the representative error codes in which the same error codes are grouped are displayed one by one. By doing in this way, all the abnormalities can be grasped in a shorter time. The representative error code may be displayed in accordance with the blinking cycle of FIG.

  Even if the selection switch 41 is operated when the device identification number is turned on or off, the same display operation is performed.

  The reference time determined to be a long press may be set to a time other than 200 ms.

  You may use for the fire receiver of an automatic fire alarm system, the receiver for crime prevention, etc.

  The state detection unit 10 is an example of a state detection unit that detects the state of each terminal connected to the monitoring control panel or the monitoring control panel.

  The selection switch 41 is an example of a selection switch for selecting a display pattern for displaying an error code for specifying an abnormality content or the above-described error code and a device identification number that is a number for identifying an abnormal device on a display.

  The main control means 20 is a control means for displaying the error code and the device identification number on a display unit according to the state detected by the state detection means, and the selection is performed when an abnormality has occurred. It is an example of the control means which displays only an error code by inputting a switch for the first time.
